What happens when you mix one of the strongest 3D printing filaments—polycarbonate—with Teflon? In this video, I review Spectrum's PC+PTFE filament to find out how this unique blend performs. From printability and shrinkage to detailed mechanical testing, I put this material through my usual series of tests to see if the addition of PTFE really makes a difference.
If you're looking for a filament that promises strength, wear resistance, and low friction, this might just be it—but let’s see what the numbers say.
